Abstract

PURPOSE:To allow the provision of playing sounds with stresses with a specified beating force and to allow the easy provision of the playing sounds with the stresses regardless of the player's skill by beating a triangle with a tapered part. CONSTITUTION:A triangle beater 1 is made into an approximate bar shape and is formed by integrally providing a middle-diameter part (gripping part) 3 at one end in the longitudinal direction of a circular cylindrical small-diameter part 7 and integrally providing a large-diameter part (beating part) 5 at the other end of the small-diameter part 7. The centroid G of the triangle beater 1 is positioned in the central part of the longitudinal direction and is so set that the operability is additionally improved. The performance technique similar to the conventional technique is, therefore, executable if the triangle 2 is beaten by the circular cylindrical part 5B or the middle-diameter part 3. On the other hand, the playing sounds increase gradually if the triangle 2 is beaten with the specified force while the triangle beater 1 is gradually moved in an arrow A direction in the case of beating the triangle with the tapered part 5A. The playing sounds are easily provided with the stresses in this way regardless of the player's skill.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a triangle beater that produces sound by hitting a triangle, and by providing a tapered portion in the hitting portion, the strength of the sound played can be easily adjusted. This is what I did.

<Prior art> Conventional triangle beaters include those that are made of a round metal bar, those that have a non-slip material such as rubber wrapped around and fixed to the grip portion of the round bar, or those that have a grip of a round bar. The side edge is U
There are known devices that extend in the shape of a letter and can be hung at an appropriate location when not in use.

Since the outer diameter of the striking part formed in these conventional triangle beaters is approximately constant, for example, when the intensity of the performance sound is gradually changed, such as in cresciendo, diminuent, or cresciendo, engineering, diminuent, The extent of the change is determined solely by the playing skill of the performer.

<Problems to be Solved by the Invention> That is, such a playing technique is performed by gradually increasing or decreasing the striking force when striking a triangle with a triangle beater.

Therefore, it is extremely difficult for young people (infants, children) and other people with inexperienced playing skills, and even for experienced players who have acquired professional-level skills, the performance is extremely burdensome. Was.

An object of the present invention is to provide a triangle beater that allows the player to easily add intensity to the performance sound, regardless of the skill of the player.

<Means for Solving the Problems> In order to achieve the above object, the triangle beater according to the present invention has a taper formed by gradually increasing the outer diameter from the base on the grip side toward the other end. It is characterized in that a striking part having a shaped part is formed.

<Function> In the triangle beater according to the present invention, by moving the striking point along the tapered part and hitting the triangle with the tapered part, it is possible to add intensity to the performance sound with a constant striking force. becomes.

<Embodiments> Hereinafter, preferred embodiments of the triangle heater according to the present invention will be described based on the drawings.

In FIG. 1, the triangle heater 1 is approximately rod-shaped, and a medium diameter portion (gripping portion) 3 is integrally provided at one longitudinal end of a cylindrical narrow diameter portion 7. It is formed by integrally providing a large diameter part (impacting part) 5 at the end.

The outer diameter of the narrow diameter portion 7 is 4 [m1Tl], and the length is 51 [mml].
The outer diameter of the middle diameter part 3 is 6 mm and the length is 62 mm.
[mml], and the length of the large diameter part 5 is roughly 57 [
mm, ].

The center of gravity G of the triangle beater 1 is set at the center in the longitudinal direction, and is set so as to further improve the operability without giving the player a sense of discomfort.

Further, in this embodiment, the material of the triangle beater 1 is carbon tool steel (SK3; JIS G4401), but the material may be brass (Cu-Zn) or pure copper (Cu).
Alternatively, it is also suitable to change the tone by using phosphor bronze (Cu-5n) or the like.

Here, the large diameter part 5 has an outer diameter of 4 from the base of the three medium diameter parts, that is, from the boundary part of the small diameter part 7 toward the other end.
A tapered portion 5A with a length of 37 mm formed by gradually expanding from mml to 7 mm and an outer diameter of 7 mm and a length of 20 mm formed integrally with the tapered portion 5A.
[It is composed of a columnar part 5B of [mml].

In this embodiment, the cylindrical part 5B with a constant outer diameter is formed, but only the tapered part 5A is formed without the cylindrical part 5B, and the volume can be adjusted according to the hitting position. It may be possible to do so.

Since the triangle beater 1 in this embodiment is constructed as described above, as can be understood from FIG. I can do the technique.

On the other hand, when striking the triangle 2 with the tapered portion 5A, if the triangle beater 1 is struck with a constant force while gradually moving in the direction of the arrow in FIG. 2, the playing sound will gradually increase from mezzo piano mp to mezzo forte mf. (crescendo), and conversely, if the triangle beater 1 is struck with a constant force while gradually moving in the direction of arrow B, the performance sound will gradually become smaller from mf to mp (diminuent).

The reason for this is that when the triangle beater 1 is moved as described above, the part of the tapered part 5A that corresponds to the swing support point 0 and the triangle 2, where the player holds the middle diameter part 3 and swings the triangle beater 1 when hitting the ball. (Strike point D)
This is because as the distance between the impact point and the impact point changes, the mass of the impact point also changes, and as a result, the angular momentum around the swing support point 0 at the impact point changes.

Therefore, by simply moving the triangle beater 1 gradually in the direction of the arrow A or B and hitting it with a constant force, the strength of the performance sound can be changed.

On the other hand, as understood from Figure 3, when hitting the triangle 2 with the medium diameter part 3 or the narrow diameter part 7, the medium diameter part 3
If you hit with the small diameter part 7, you can accurately produce the sound of the forte f, and if you hit with the narrow diameter part 7, you can accurately produce the mezzo piano rnp.

Furthermore, since the center of gravity G is located approximately at the center in the longitudinal direction of the triangle 2, it is possible to easily change the grip between the medium diameter section 3 and the large diameter section 5. By changing the grip and hitting the ball with the cylindrical portion 5B of the large diameter portion 5, it is possible to perform a performance that accurately distinguishes between forte f and fortissimo ff.

In this way, in the past, performance required a plurality of triangle beaters, each with a different diameter, corresponding to the strength of the percussion sound ranging from pianosimo pp to fortissimo ff, but in this embodiment, the medium diameter section 3 and the narrow diameter section 3 are used. 1 having a portion 7 and a large diameter portion 5
This can be done relatively easily by changing the book triangle beater 1.

As described above, in this embodiment, the tapered portion 5A is formed in the large diameter portion 5.

Therefore, by simply moving the triangle beater 1 in the direction of arrow A or B and hitting it with a constant force, you can add strength or weakness to the performance sound. It can be easily done without any involvement.

Therefore, it is suitable for use as an educational instrument for beginners (infants, children, etc.), and it is also suitable for use as an educational instrument for beginners (infants, children, etc.).It also greatly reduces the burden on musicians with professional-level playing skills, so it is suitable for use as an educational instrument for beginners (infants, children, etc.). It becomes possible to develop it into a performance.

<Effects of the Invention> As understood from the above explanation, in the triangle beater according to the present invention, by hitting the triangle with the tapered part, it is possible to vary the strength of the performance sound with a constant hitting force. .

Therefore, it is easy to adjust the dynamics of the performance sound regardless of the skill of the performer.

As a result, operability and playability can be improved without causing discomfort to players who have been using conventional triangle beaters.
